+## [1.3.0] - 2026-09-01
+
+### Added
+
+- `IModuleEnvironmentProvider`, the hook a test framework integration uses to put a test under
+  the environment it declares. Module conditions - `[IfEnvironment]` and its siblings - are
+  evaluated as registrations are applied, and both runners load modules before the service-setup
+  pass by design, so an environment registered there arrived after every condition had been
+  decided against the process default. The runners now consult the new interface before any
+  module is applied, widest scope first, narrowest answer deciding. A minor version, because the
+  Runtime package gains public API.

 ## [1.2.3] - 2026-08-29
